Thread class: Added new methods (POSIX implementation only yet):

* Added methods pushCancelable() and popCancelable() for allowing to
  prevent thread being terminated on critical sections.

* Added methods name(), nameOfCaller() and setNameOfCaller() to allow
  assigning threads human readable names for debugging purposes.

* configure: Always check for availability of pthread_testcancel()
  and use it if so (previously it was only used if explicitly enabled
  by configure script option).

* Raise a compiler warning if pthread_testcancel() is not available.

* Bumped version (2.1.1.svn52).

1 Version SVN trunk (?)

3 * general changes:
4 - Fixed compiler error in Pool.h.
5 - Require C++14 compiler support.
6 - Autoconf: Added m4/ax_cxx_compile_stdcxx.m4 macro which is used
7 for checking in configure for C++14 support (as mandatory
8 requirement) and automatically adds compiler argument if required
9 (e.g. -std=C++14).
10 - RTMath: Implemented floating point comparison methods
11 fEqual32(float,float) and fEqual64(double,double) which take the
12 expected floating point tolerances into account.
13 - Added public API C++ class "LFO", which is a cluster class encapsulating
14 all the sampler's LFO implementations to be used by 3rd party applications
15 (e.g. by Gigedit).
16 - Added int math square LFO implementation.
17 - Added int math saw LFO implementation.
18 - Added numeric complex nr sine LFO implementation.
19 - Marked class LFOTriangleDiHarmonic as deprecated
20 (will be removed in future).
21 - Added LFOAll.h which includes all LFO implementation's header files.
22 - Refactored LFO class names and their file names (PulseLFO -> LFOPulse,
23 LFOSawIntMath -> LFOSawIntMathNew, SawLFO -> LFOSawIntMathOld,
24 SineLFO -> LFOSineBuiltinFn, LFOSine -> LFOSineNumericComplexNr,
25 SquareLFO -> LFOSquarePulse and separated the latter to its own header
26 file).
27 - Renamed type LFOSigned -> LFOTriangleSigned.
28 - Renamed type LFOUnsigned -> LFOTriangleUnsigned.
29 - Using now cubic interpolation as resampling algorithm by default; and
30 linear interpolation is deprecated now.
31 - Event:Init(): memset() entire Event::Param union to zero instead of trying
32 to do that for its individual members; the latter became error prone due
33 to the union's growing complexity meanwhile.
34 - EngineChannel: Overhaul of RPN/NRPN related methods: Added new
35 *Rpn*Parameter*() methods as replacement for previous *Rpn*Controller*()
36 methods and marked the old ones as deprecated; and likewise added new
37 *Nrpn*Parameter*() methods as replacement for previous *Nrpn*Controller*()
38 methods and marked those old ones deprecated as well.
39 - Added support for MIDI CC #38 (data entry LSB): this allows higher value
40 resolution for certain (e.g. hard coded) RPN and NRPN parameters.
41 - Implemented support for compressed RPN/NRPN message sequences (that is to
42 allow processing MIDI data entry messages without always having to be
43 preceded strictly by RPN/NRPN parameter selection messages on each value
44 change).
45 - Added support for MIDI CC #96 (data increment) and MIDI CC #97 (data
46 decrement).
47 - Added support for 'null function RPN/NRPN' (which is RPN/NRPN parameter
48 MSB=127 and LSB=127) and which is disabling subsequent data
49 entry/increment/decrement CC messages.
50 - Fixed crash when editing key groups (a.k.a. exclusive groups) with an
51 instrument editor.
52 - Fixed playing noise at the end of a disk stream under certain conditions.
53 - Fixed potential crash with high pitch at end of RAM playback.
54 - Added configure checks whether C++ compiler supports so called
55 'designated initializers'.
56 - Added global backtraceAsString() function for debugging purposes
57 (POSIX systems only, no Windows implementation yet).
58 - Thread class: Added new methods pushCancelable(), popCancelable(), name(),
59 nameOfCaller() and setNameOfCaller().
60 - configure: Always check for availability of pthread_testcancel() and use
61 it if so (previously it was only used if explicitly enabled by configure
62 option).
63 - Thread class: raise compiler warning if pthread_testcancel() is not
64 available, because it can lead to deadlocks.
65
66 * Real-time instrument scripts:
67 - Added method ScriptVM::setExitResultEnabled() which allows to
68 explicitly enable the built-in exit() function to optionally accept
69 one function argument; the value of the passed exit() function
70 argument will then become available by calling
71 VMExecContext::exitResult() after script execution.
72 - 64 bit support for NKSP integer scripts variables (declare $foo).
73 - Variable names, function names and preprocessor condition names must start
74 with a regular character (a-z or A-Z); starting them with a digit or
75 underscore is not allowed.
76 - NKSP parser fix: equal comparison operator "=" and not equal comparison
77 operator "#" must only accept integer operands.
78 - NKSP language: Implemented support for standard units like Hertz, seconds,
79 Bel including support for metric unit prefixes; so one can now e.g.
80 conveniently use numbers in scripts like "5us" meaning "5 microseconds",
81 or e.g. "12kHz" meaning "12 kilo Hertz", or e.g. "-14mdB" meaning
82 "minus 14 Millidecibel", or e.g. "28c" meaning "28 cents" (for tuning).
83 - NKSP language: Introduced "final" operator "!" which is specifically
84 intended for synthesis parameter values to denote that the synthesis
85 parameter value is intended to be the "final" value for that synthesis
86 parameter that should explicitly be used by the engine and thus causing
87 the sampler engine to ignore all other modulation sources for the same
88 synthesis parameter (like e.g. LFO, EG); by simply prefixing a value,
89 variable or formula with this new "!" operator the expression is marked as
90 being "final".
91 - NKSP script editor API: Added support for detecting standard unit tokens
92 and their potential metric prefix token.
93 - NKSP language: Added support for NKSP real number literals and
94 arithmetic operations on them (e.g. "(3.9 + 2.9) / 12.3 - 42.0").
95 - NKSP language: Added support for NKSP real number (floating point) script
96 variables (declare ~foo).
97 - NKSP language: Added support for NKSP real number (floating point) array
98 script variables (declare ?foo[]).
99 - Built-in script function "message()" accepts now real number argument as
100 well.
101 - Added built-in script function "real_to_int()" and its short hand form
102 "int()" for casting from real number to integer in NKSP scripts.
103 - Added built-in script function "int_to_real()" and its short hand form
104 "real()" for casting from integer to real number in NKSP scripts.
105 - Allow built-in exit() function to potentially accept real number type
106 argument as well.
107 - Built-in script functions may have a different return type depending on
108 the arguments passed to the function.
109 - Built-in script function "abs()" optionally accepts and returns real
110 number.
111 - Built-in script functions "min()" and "max()" optionally accept real
112 number arguments and return real number as result in that case.
113 - NKSP VM API: Allow units and 'final'ness to be returned as result from
114 built-in functions (added methods VMFunction::returnUnitType() and
115 VMFunction::returnsFinal() for that purpose which must be implemented by
116 built-in function implementations).
117 - NKSP language: Allow metric unit prefixes of numeric scalar and array
118 variables to be changed freely at runtime (unlike unit types like Hz etc.
119 which are still sticky, parse-time features of variables which cannot be
120 changed at runtime for the intentional sake of determinism).
121 - NKSP language: 'final' values are prohibited for array variables for now
122 (attempt causes a parsers error).
123 - NKSP language: expressions with unit types (e.g. Hz) are prohibited for
124 conditions of runtime control structures like if(), while(), select()
125 (attempt causes a parser error).
126 - NKSP VM API: Allow built-in functions to perform their own, individual
127 parse time checks of arguments going to be passed to the function at
128 runtime (added method VMFunction::checkArgs() for that purpose).
129 - NKSP language: raise parser warning if only one operand of binary
130 operators (like logical 'or' comparison) contain a 'final' value (because
131 it would always yield in a 'final' result in such cases).
132 - NKSP language: Allow comparison (=, #, <, >, <=, >=) of values with
133 different metric unit prefixes, which will behave as expected (e.g.
134 result of expression '1000us < 2ms' is true).
135 - NKSP language: Allow adding values with different metric unit prefixes
136 (e.g. result of expression '100Hz + 5kHz' is '5100Hz').
137 - NKSP language: Allow subtracting values with different metric unit
138 prefixes (e.g. result of expression '1ms - 20us' is '980us').
139 - NKSP language: Allow multiplying with any metric unit prefixes
140 (e.g. result of expression '2k * 3ms' is '6s'), however multiplications
141 with unit types on both sides (e.g. '2s * 2s') is still prohibited since
142 we don't have any considerable practical use for a term like '4s^2'
143 (hence any attempt multiplying two unit types still causes parser error).
144 - NKSP language: Allow dividing by any metric unit prefixes and allow
145 division of same unit type on both sides (e.g. expression '8kHz / 1000Hz'
146 yields in unit free result '8'). So this is now a way to cast units away
147 e.g. for passing the result to other expressions, certain function calls
148 or variables which are not accepting any units (or that specific unit).
149 - NKSP language: integer arrays and real number arrays can now be converted
150 to strings (e.g. for dumping their content with message() calls for
151 script debugging purposes).
152 - NKSP language: expressions and variables with units are now correctly
153 casted to strings (e.g. with message() calls).
154 - NKSP language: comparing real numbers for equalness (e.g. '~foo = 3.1') or
155 unequalness (e.g. '~foo # 3.1') is now less strict and takes the expected
156 floating point tolerances into account.
157 - NKSP VM API: Added methods VMScalarNumberExpr::evalCastInt() and
158 VMScalarNumberExpr::evalCastReal().
159 - NKSP VM API: Added base class 'VMNumberArrayExpr' for classes
160 'VMIntArrayExpr' and 'VMRealArrayExpr'.
161 - NKSP VM API: replaced all unitPrefix() (parse time) methods by
162 unitFactor() (runtime) methods.
163 - Built-in function "exit()" supports now returning units and 'final'ness
164 for test cases.
165 - The following built-in functions support now units as well: "abs()",
166 "random()", "inc()", "dec()", "in_range()", "min()", "max()",
167 "real_to_int()", "int()", "int_to_real()" and "real()".
168 - Built-in functions "array_equal()", "search()" and "sort()" support now
169 real number arrays (correctly) as well.
170 - Added individual parse time checks of arguments to be passed to built-in
171 functions "random()", "inc()", "dec()", "in_range()", "min()", "max()",
172 "array_equal()" and "search()" specific for their individual purposes.
173 - NKSP VM refactoring: Renamed all methods, functions and classes matching
174 pattern *ScalarNumber* to simply *Number* (that is i.e. classes
175 VMScalarNumberExpr -> VMNumberExpr, ScalarNumberExpr -> NumberExpr,
176 ScalarNumberVariable -> NumberVariable, ScalarNumberBinaryOp ->
177 NumberBinaryOp, VMScalarNumberResultFunction -> VMNumberResultFunction,
178 method VMExpr::asScalarNumberExpr() -> VMExpr::asNumber(), function
179 isScalarNumber() -> isNumber()).
180 - NKSP VM API: Added 4 overridden methods to class VMNumberExpr:
181 evalCastInt(MetricPrefix_t), evalCastInt(MetricPrefix_t,MetricPrefix_t),
182 evalCastReal(MetricPrefix_t), evalCastReal(MetricPrefix_t,MetricPrefix_t)
183 as convenient methods for automatically converting values to expected
184 metric value basis.
185 - Built-in function "wait()" accepts now both integers and real numbers as
186 argument.
187 - NKSP VM API cleanup: Get rid of legacy method
188 VMFunction::argType(vmint iArg) which was already superseded by its new
189 replacement VMFunction::acceptsArgType(vmint iArg, ExprType_t type).
190 - NKSP parser: if wrong argument type was passed to a built-in function and
191 that built-in function accepts more than one data type for the argument,
192 then show all supported data types as parser error message.
193 - Built-in function "play_note()" accepts now real numbers and seconds as
194 unit type as well for its 3rd and 4th function arguments.
195 - The following built-in functions accept now real numbers as well for their
196 2nd function argument: "change_vol()", "change_tune()", "change_cutoff()",
197 "change_attack()", "change_decay()", "change_release()",
198 "change_sustain()", "change_cutoff_attack()", "change_cutoff_decay()",
199 "change_cutoff_sustain()", "change_cutoff_release()",
200 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
201 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
202 "change_pan_time()", "fade_in()", "fade_out()", "change_play_pos()".
203 - Fixed built-in function "change_play_pos()" not having accepted metric
204 prefixes at all.
205 - Fixed the following built-in functions having misinterpreted values given
206 with unit type (for their 2nd argument) as if they were relative values
207 (that is as if they were passed without a unit type): "change_attack()",
208 "change_decay()", "change_release()", "change_cutoff_attack()",
209 "change_cutoff_decay()", "change_cutoff_release()".
210 - Fixed the following built-in functions having applied completely wrong
211 'final' values: "change_sustain()", "change_cutoff_sustain()" (since the
212 respective EGs being their modulation sink assume uint data type with
213 value range 0..1000 instead of 0.0..1.0.
214 - Added individual parse-time checks of function arguments for the following
215 built-in functions: "play_note()", "note_off()", "set_event_mark()",
216 "delete_event_mark()", "by_marks()", "change_cutoff()", "change_attack()",
217 "change_decay()", "change_release()", "change_cutoff_attack()",
218 "change_cutoff_decay()", "change_cutoff_release()",
219 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
220 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()" and
221 "change_pan_time()".
222 - Don't abort function call if unit type was used and at the same time
223 'final' operator was omitted for the primary value argument of the
224 following built-in functions: "change_cutoff()", "change_attack()",
225 "change_decay()", "change_release()", "change_cutoff_attack()",
226 "change_cutoff_decay()", "change_cutoff_release()",
227 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
228 "change_pitch_lfo_freq()", "change_vol_time()", "change_tune_time()",
229 "change_pan_time()", instead imply 'final'ness at runtime and raise an
230 appropriate parser warning at parse time.
231 - Added built-in real number functions "round()", "ceil()", "floor()",
232 "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()", "sin()",
233 "cos()", "tan()", "asin()", "acos()", "atan()".
234 - Added built-in script real number constant "~NI_MATH_PI".
235 - Added built-in script real number constant "~NI_MATH_E".
236 - NKSP language: Allow unary '+' operator.
237 - Added built-in script functions "msb()" and "lsb()".
238 - NKSP language: Added support for RPN event handler
239 ("on rpn ... end on" in instrument scripts).
240 - NKSP language: Added support for NRPN event handler
241 ("on nrpn ... end on" in instrument scripts).
242 - Added built-in read-only variables "$RPN_ADDRESS" and "$RPN_VALUE" which
243 may be read from the new RPN/NRPN script handlers to get the (N)RPN
244 parameter that had been changed and its new value.
245 - Added built-in const variables "$NI_CB_TYPE_RPN" and "$NI_CB_TYPE_NRPN"
246 which are identifying the new (N)RPN handlers as such at script runtime.
247 - Implemented built-in script function "set_rpn()".
248 - Implemented built-in script function "set_nrpn()".
249 - Fix: built-in functions returning an array type were broken and caused a
250 crash when the built-in function's (supposed to be array) result value was
251 used by the script VM.
252 - Removed upper value constraint for 2nd argument of built-in functions
253 "change_amp_lfo_freq()", "change_cutoff_lfo_freq()",
254 "change_pitch_lfo_freq()","change_reso()", "change_cutoff()",
255 "change_amp_lfo_depth()", "change_cutoff_lfo_depth()" and
256 "change_pitch_lfo_depth()", to allow e.g. passing value 2000000 to double
257 the LFO frequency / resonance / cutoff frequency.
258 - Reduced code involved for parsing NKSP variable declarations by using 2
259 generalized grammar rules with optional components (i.e. optional value
260 assignment and optional variable qualifiers) instead of previous linear
261 combinations of grammar rules, which also fixes some edge case.
262 - NKSP language parser: track code block locations also by a) raw byte
263 position in NKSP source code string and b) length of that code block in
264 bytes (along to the already existing code block tracking by line/column);
265 and added appropriate new members to public C++ API classes like
266 'firstByte' and 'lengthBytes' to class VMSourceToken and struct CodeBlock.
267 - NKSP language: Added support for 'patch' variable qualifier (capture their
268 locations and allow replacement of their assignment expression via VM C++
269 API).
270 - Fixed incorrect EG times if standard measuring unit was passed to built-in
271 functions "change_attack()", "change_decay()" or "change_release()".
272 - Fixed intermediate function result values never having reflected any
273 standard measuring unit type.
274 - Fixed re-entrant issue with function calls which caused wrong result
275 values if the same function was called multiple times in a term
276 (specifically if metric prefixes were used).
277
278 * test cases:
279 - Fixed compiler errors in test cases.
280 - Updated README for how to compile & run test cases.
281 - Updated test case
282 MutexTest::testDoubleLockStillBlocksConcurrentThread() to latest
283 expected behaviour of the Mutex class implementation (recursive
284 mutex type).
285 - Added test cases for NKSP core language aspects and core built-in
286 functions.
287 - Fixed thread tests segfaulting on Linux.
288 - NKSP: Added real number test cases for built-in functions exit(),
289 int_to_real(), real(), real_to_int() and int(), as well as for the
290 plus, minus and negate language operators.
291 - Added massive amount of NKSP test cases for standard measuring units and
292 'final' operator usage cases.
293 - Added NKSP test cases for (floating point tolerance aware) real number
294 equalness / unequalness comparison.
295 - Added NKSP int array and real array tests for value assignment and
296 initialization of arrays.
297 - Added NKSP test cases for built-in functions "round()", "ceil()",
298 "floor()", "sqrt()", "log()", "log2()", "log10()", "exp()", "pow()",
299 "sin()", "cos()", "tan()", "asin()", "acos()", "atan()".
300 - Added NKSP test cases for unary '+' operator.
301 - Added NKSP test cases for core built-in variables.
302 - Added thorough NKSP test cases for variable declarations.
303
304 * GigaStudio/Gigasampler format engine:
305 - LFOTriangleIntMath and LFOTriangleIntAbsMath: Fixed FlipPhase=true
306 behaviour for start_level_mid.
307 - Changed LFO start levels: LFO1 and LFO2 both to mid, LFO3 to max. start
308 level (see discussion "GigaStudio LFO compatibility" on mailing list
309 from 2019-09-26 for details).
310 - Changed default wave form for all 3 LFOs to sine (instead of triangle;
311 see discussion "GigaStudio LFO compatibility" on mailing list from
312 2019-09-26 for details).
313 - Format extension: Added support for different LFO wave forms (currently
314 either sine [default], triangle, saw or square).
315 - Format extension: Added support for LFO phase displacement (0��..360��).
316 - Format extension: Added support for flipping LFO polarity on LFO 3
317 (in the original gig format this was only available for LFO 1 and LFO 2).
318 - Format extension: Support for additional filter types:
319 lowpass 1/2/4/6-pole, highpass 1/2/4/6-pole, bandpass 2-pole,
320 bandreject 2-pole.
321 - Fixd potential crash with polynomial interpolator and max. pitch.
322 - If minimum cutoff is defined, remap cutoff controller CC values to really
323 span the entire possible cutoff range (and avoiding a dead controller
324 zone).
325 - Implemented support for loading instrument scripts with 'patch' variables
326 (by patching these script variables with potentially overridden ones by
327 gig Instrument).
328
329 * SFZ format engine:
330 - Fixed support for regions with loccN/hiccN conditions on more than one
331 MIDI controller.
332
333 * Benchmarks:
334 - Fixed benchmarks/triang.cpp falsely having favoured "int math abs"
335 algorithm (since result of 2nd run was not accumulated).
336 - Added benchmark for saw wave (benchmarks/saw.cpp).
337 - Added benchmark for sine wave (benchmarks/sine.cpp).
338 - Added benchmark for square wave (benchmarks/square.cpp).
339 - Increased amount of benchmarks runs by factor 6 to achieve benchmark times
340 which are large enough on modern systems.
341
342 Version 2.1.1 (27 Jul 2019)
343
344 * Real-time instrument scripts:
345 - Fixed behavior of built-in NKSP functions change_sustain(),
346 change_cutoff_attack(), change_cutoff_decay(), change_cutoff_sustain()
347 and change_cutoff_release().
348
349 * general changes:
350 - Only play release trigger samples on sustain pedal up if this behaviour
351 was explicitly requested by the instrument (otherwise only on note-off).
352 - Fixed compiler warnings.
353 - Fixed compilation error when cross-compiling to Mac.
354 - FX Sends: Provide more useful error messages on routing problems
355 (see bug #169).
356 - LSCP doc: Be more clear describing the two distinct approaches
357 of using external vs. internal effects (see bug #169).
358 - "optional" class: Fixed comparison operators.
359
360 * Gigasampler/GigaStudio format engine:
361 - Format extension: If requested by instrument then don't play release
362 trigger sample on note-off events.
363
364 * SFZ format engine:
365 - Fixed memory leak when releasing samples
366 (fixes bug #307, patch by Jacek Roszkowski)
367 - Fixed potential crash when a sample is shared by more than one region
368 (fixes bug #308, patch by Jacek Roszkowski).
369 - Opcode 'sample': Added support for built-in sample '*silence'
370 (fixes bug #310, patch by Jacek Roszkowski).
371
372 Version 2.1.0 (25 Nov 2017)
373
374 * SFZ format engine:
375 - added support for <global>, <master> and #define (patch by Alby M)
376 - Removed code duplication in SFZ file loading code.
377 - Added support for sfz extension opcode 'script' which may be used to
378 load real-time instrument script file (NKSP script language).
379 - Implemented opcode set_ccN (initial patch by Giovanni Senatore).
380 - Fixed unintended volume fade-in of voices under certain conditions.
381 - sfz parser: allow missing space between header and opcode
382
383 * Gigasampler/GigaStudio format engine:
384 - Fixed clicks and pumping noise with Lowpass Turbo filter on very low
385 cutoff settings.
386 - Got rid of resembling an ancient GSt misbehavior which did not pitch at
387 all if an up-pitch of more than 40 semi tones was requested (I don't
388 think there is any stock gig sound that requires this behavior to
389 resemble its original sound).
390 - Added support for controlling whether the individual EGADSR stages may
391 be aborted (as LinuxSampler extension to the original GigaStudio 4
392 format).
393
394 * general changes:
395 - fixed printf type errors (mostly in debug messages)
396 - use unique_ptr instead of auto_ptr when building with C++11
397 - Added RTAVLTree class which is a real-time safe ordered multi-map, thus
398 allowing to sort data efficiently in real-time safe manner.
399 - RTList class: added methods for moving/inserting elements to arbitrary
400 position within a list.
401 - RTList class: added method fromPtr() for creating an Iterator object from
402 a raw element pointer.
403 - Attempt to partly fix resetting engine channels vs. resetting engine, an
404 overall cleanup of the Reset*(), ConnectAudioDevice(),
405 DisconnectAudioDevice() API methods would still be desirable though,
406 because the current situation is still inconsistent and error prone.
407 - Active voices are now internally grouped to "Note" objects, instead of
408 being directly assigned to a keyboard key. This allows more fine graded
409 processing of voices, which is i.e. required for certain instrument
410 script features.
411 - Fix: Release trigger voices were not spawned on sustain pedal up
412 (CC #64) events.
413 - Fix: Release trigger voices can now also distinguish correctly between
414 note-off and sustain pedal up events.
415 - All engines: Increased ramp speed of volume smoother and pan smoother
416 (while slow rate of crossfade smoother is preserved) to allow quick
417 volume and pan changes by instrument scripts for instance.
418 - gig/sf2/sfz: Fixed aftertouch channel pressure events being processed
419 properly and thus were ignored for certain uses.
420 - Added new C++ API method
421 VirtualMidiDevice::SendChannelPressureToSampler().
422 - windows, 32-bit: fixed potential crashes by making sure the stack in
423 sub threads is 16-byte aligned
424 - fixed numerous compiler warnings
425 - Fixed invalid (note-on) event ID being assigned to new Note objects.
426 - Revised fundamental C++ classes "Thread", "Mutex" and "Condition" which
427 fixes potential undefined behavior.
428 - Fixed Note object leak when triggering notes on keys which did not
429 have a valid sample mapped (fixes bug #252).
430 - Fixed compilation errors when compiling with CONFIG_DEVMODE enabled.
431 - linuxsampler binary fix: option --create-instruments-db ignored
432 subsequent optional argument due to glibc's implementation oddity
433 which expects a "=" sign, but no space between them.
434
435 * packaging changes:
436 - removed unnecessary dependency to libuuid
437 (originated by libgig's usage of it)
438 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
439 auto detect whether it (sh/c)ould output its messages in color.
440 - Debian: Fixed packaging error about invalid "Source-Version"
441 substitution variable.
442 - Debian: Raised Debian compatibility level to Debian 9 "Stretch".

444 linuxsampler with instruments DB support.
445
446 * Real-time instrument scripts:
447 - Implemented scheduler for delayed MIDI events and for suspended scripts.
448 - Built-in script function "wait()": implemented support for function's
449 "duration-us" argument, thus scripts using this function are now
450 correctly resumed after the requested amount of microseconds.
451 - Built-in script function "play_note()": implemented support for
452 function's "duration-us" argument, thus notes triggered with this
453 argument are now correctly released after the requested amount of
454 microseconds.
455 - Fix: script events were not cleared when engine channel was reset,
456 potentially causing undefined behavior.
457 - Fixed crash which happened when trying to reference an undeclared
458 variable.
459 - Built-in script function "play_note()": Added support for passing
460 special value -1 for "duration-us" argument, which will cause the
461 triggered note to be released once the original note was released.
462 - Instrument script classes now exported with the liblinuxsampler C++ API.
463 - Added new API method ScriptVM::syntaxHighlighting() which provides
464 a convenient syntax highlighting backend for external instrument
465 script editor applications.
466 - Added new C++ API class "ScriptVMFactory".
467 - Extended parser issues to provide not only first line and first
468 column, but also last line and last column of issue (thus marking
469 the precise span of the issue within the source code).
470 - Reload script automatically after being modified by an instrument
471 editor.
472 - NKSP language grammar correction: allow empty event handler bodies
473 like "on note end on".

479 - Implemented built-in script function "event_status()".
480 - Added built-in script constants "$EVENT_STATUS_INACTIVE" and
481 "$EVENT_STATUS_NOTE_QUEUE" both for being used as flags for
482 "event_status()" function.
483 - NKSP language: Added support for bitwise operators ".or.", ".and."
484 and ".not.".
485 - NKSP language scanner: Fixed IDs matching to require at least one
486 character (i.e. when matching function names or variable names).
487 - NKSP language scanner: disabled unusued rules.
488 - Fixed behavior of play_note() and note_off() functions which must
489 be distinguished engine internally from "real" MIDI note on/off
490 events in order to avoid misbehaviors like hanging notes.
491 - Implemented built-in script variable "$KSP_TIMER".
492 - Implemented built-in script variable "$NKSP_REAL_TIMER".
493 - Implemented built-in script variable "$NKSP_PERF_TIMER".

497 - NKSP language fix: division expressions were evaluated too often.
498 - NKSP language fix: string concatenation operator was right
499 associative instead of left (to right).
500 - NKSP language correction: allow empty statements in entire language
501 (i.e. "if end if").
502 - Implemented built-in script function "stop_wait()".

514 - Implemented built-in script function "change_decay()".
515 - Implemented built-in script function "change_release()".
516 - Fixed all change_*() built-in script functions to apply their
517 synthesis parameter changes immediately in case the respective note
518 was triggered at the same time, instead of scheduling the parameter
519 change, especially because it would cause some parameter types's
520 changes either to be ramped (i.e. change_vol()) or other types even
521 to have not effect at all (i.e. change_attack()).
522 - Implemented built-in script function "sh_left()".
523 - Implemented built-in script function "sh_right()".
524 - Implemented built-in script function "min()".
525 - Implemented built-in script function "max()".
526 - NKSP Fix: "init" event handler was not always executed when a script
527 was loaded.
528 - NKSP built-in wait() script function: abort script execution if
529 a negative or zero wait time was passed as argument (since this is
530 a common indication of a bug either of the script or even of the
531 engine, which could lead to RT instability or even worse).
532 - ScriptVM: Implemented automatic suspension of RT safety
533 threatening scripts.
534 - Provide more user friendly error messages on syntax errors.
535 - Fixed NKSP parser warning "Not a statement" when assigning an
536 initializer list to an array variable.

543 - Implemented built-in script function "change_vol_time()".
544 - Implemented built-in script function "change_tune_time()".
545 - Implemented built-in script function "fade_in()".
546 - Implemented built-in script function "fade_out()".
547 - Fixed acceptance of wrong data type of parameters passed to built-in
548 script functions "change_vol()", "change_tune()", "change_pan()",
549 "change_cutoff()", "change_reso()", "change_attack()", "change_decay()",
550 "change_release()", "change_amp_lfo_depth()", "change_amp_lfo_freq()",
551 "change_pitch_lfo_depth()" and "change_pitch_lfo_freq()".
552 - Added built-in script function "get_event_par()" and implemented some
553 of its possible parameter selections.
554 - Added built-in script function "set_event_par()" and implemented some
555 of its possible parameter selections.
556 - Fixed a bunch of scheduler time related bugs.
557 - Fixed polyphonic variables not being reset to zero after usage.
558 - Built-in "ignore_event()" function: argument is now optional, like with
559 built-in function "ignore_controller()".
560 - Implemented built-in script function "change_velo()".
561 - Implemented built-in script function "change_note()".
562 - Adjusted behavior of "change_vol()" and "change_tune()" to a more
563 intuitive behavior if used in combination with "change_vol_time()" or
564 "change_tune_time()" respectively: now tuning/volume changes are only
565 assigned (without delay) immediately to a new note if the respective
566 timing function has not been called before, otherwise the volume/tuning
567 changes are automatically faded (before, only the event's time stamp was
568 relevant).
569 - Implemented built-in script function "array_equal()".
570 - Implemented built-in script function "search()".
571 - Implemented built-in script function "sort()".
572 - NKSP Fix: Never suspend "init" event handlers.
573 - Implemented built-in script function "same_region()" (currently only
574 available for gig format engine).
575 - Added built-in script constant "$NKSP_LINEAR".
576 - Added built-in script constant "$NKSP_EASE_IN_EASE_OUT".
577 - Implemented built-in script function "change_vol_curve()".
578 - Implemented built-in script function "change_tune_curve()".
579 - built-in "play_note()" function now supports a sample playback start
580 offset with argument 3, where special value -1 means to use the regular
581 sample offset as defined by the instrument file.
582 - Built-in array variable %KEY_DOWN[] is now a read-only variable.
583 - Built-in variable $EVENT_NOTE is now a read-only variable.
584 - Built-in variable $EVENT_VELOCITY is now a read-only variable.
585 - built-in "play_note()" function now accepts -2 for its fourth argument
586 (note duration) which means the life time of the note shall be sticked
587 to the requested note number of argument 1.
588 - Fix: built-in "play_note()" function now returns 0 as result value if
589 -1 was passed for its fourth argument (note duration) and the respective
590 parent note is already gone.
591 - Implemented built-in script function "change_play_pos()".
592 - NKSP language: Added support for user declared const array variables.
593 - NKSP language: Raise parser warning if array variable is accessed with
594 an index that exceeds the array's size.
595 - NKSP language fix: Unknown characters were not handled correctly.
596 - NKSP language: Added support for "synchronized .. end synchronized"
597 code blocks.
598 - Implemented built-in script function "abort()" which allows to abort
599 another script handler by passing its callback ID.
600 - Fixed potential memory access bug and potential undefined behavior of
601 "init" event handlers.
602 - Print a time stamp along to each call of built-in function "message()".
603 - ScriptVM API: Added VMParserContext::preprocessorComments() which allows
604 to retrieve all code blocks filtered out by the preprocessor.
605 - Added built-in script function "fork()".
606 - Added built-in array variable %NKSP_CALLBACK_CHILD_ID[].
607 - Added built-in variable $NKSP_CALLBACK_PARENT_ID.

609 - Added built-in script function "callback_status()".
610 - Added built-in constant $CALLBACK_STATUS_TERMINATED.
611 - Added built-in constant $CALLBACK_STATUS_QUEUE.
612 - Added built-in constant $CALLBACK_STATUS_RUNNING.
613 - Removed max. value limitation of built-in functions "change_attack()",
614 "change_decay()" and "change_release()" to i.e. allow passing 2000000
615 for doubling the respective time.
616 - NKSP script editor syntax highlighting API: Fixed app termination due
617 to a lexer start condition stack underrun.
618 - NKSP preprocessor: Fixed wrong behavior on nested USE_CODE_IF() and
619 USE_CODE_IF_NOT() preprocessor statements.
620 - NKSP: Added built-in preprocessor condition NKSP_NO_MESSAGE, which
621 can be set to disable all subsequent built-in "message()" function calls
622 on preprocessor level.
623 - Implemented built-in script function "change_sustain()".
624 - NKSP script editor syntax highlighting API: catch all fatal lexer errors,

637 undefined behavior.
638 - Cleanup of instruments DB file creation and opening code.

640 is now optional, if it is missing, then a default location is used.
641 - Added support for scanning SFZ (.sfz) files.
642 - Added support for scanning Sound Font (.sf2) files.
643 - Fixed undefined DB transaction behavior.

660 configure
661 - Mac OS X: Makefile fix for the install-strip target
662 - fixed compilation with gcc 4.7
663 - fixed configure script error with old autoconf versions
664 - lsatomic.h: use gcc provided atomic functions if building with
665 gcc 4.7 and C++11
666 - modernized configure script
667 - fixed linkage error when building with
668 LDFLAGS="-Wl,--no-undefined" (#190)
669 - fixed compilation with Clang 3.2
670 - removed usage of deprecated Automake variable INCLUDES
671 - fixed building with C++11

674 makefiles
675 - fix for building with bison 3.0 (#202)
676 - Mac OS X: added temporary hack allowing to spawn gigedit as callback
677 on the process's main thread
678 - fixed build error on newer MinGW
679 - support building with older jack versions
680 - support building with spaces in vst sdk path

683 in order to get rid of warnings from automake 1.14
684
685 * general changes:
686 - Refactoring: moved the independent code from
687 the Gigasampler format engine to base classes
688 - command line option '--profile' is currently disabled, since the
689 respective profiling code is currently broken
690 - Introduced support for optional environment variable
691 "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
692 where the sampler shall look for instrument editor plugins
693 (patch by Luis Garrido, slightly modified).
694 - implemented Roland GS NRPN 1ArrH which allows to set volume per note
695 - implemented Roland GS NRPN 1CrrH which allows to set pan per note
696 - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
697 note (in this implementation of the sampler its simply hard routed to
698 the 1st effect send of the sampler channel, no matter what the actual
699 effect type is)
700 - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
701 note (in this implementation of the sampler its simply hard routed to
702 the 2nd effect send of the sampler channel, no matter what the actual
703 effect type is)
704 - implemented support for internal LADSPA effects
705 - raised limit of program change queue from 100 to 512
706 (as suggested by Alex Stone)
707 - implemented sine LFO, pulse LFO and saw LFO
708 - experimental support for per voice equalization
709 - added command line option --exec-after-init
710 - Introduced new C++ API method:
711 EngineChannel::InstrumentFileName(int index)
712 allowing to retrieve the whole list of files used for the loaded
713 instrument on an engine channel (a.k.a. part). Some GigaStudio
714 instruments for example are splitted over several files like
715 "Foo.gig", "Foo.gx01", "Foo.gx02", ...
716 - Added new C++ API method Sampler::GetGlobalMaxVoices().
717 - Added new C++ API method Sampler::GetGlobalMaxStreams().
718 - Added new C++ API method Sampler::SetGlobalMaxVoices().
719 - Added new C++ API method Sampler::SetGlobalMaxStreams().
720 - Various "const" and "restrict" optimizations.
721 - all engines: add pan CC value to instrument pan parameter before
722 applying panning, instead of using two separate pan functions in
723 series (#182)
724 - added a lock guard class for exception safe mutex handling and
725 used it everywhere appropriate
726 - Immediately apply scale tuning changes to active voices.
727 - Exposed scale tuning to C++ API (along to the already existing standard
728 SysEx way).
729 - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
730 and broken for ppc64. (Seq_cst loads and stores are actually not
731 used in LS, so the bug wasn't noticable.)
732 - lsatomic.h: added ARMv7 support
733 - Added support for multiple MIDI input ports per sampler channel (and
734 added various new C++ methods for this new feature / design change, old
735 C++ API methods for managing SamplerChannel's MIDI inputs are now marked
736 as deprecated but are still there and should provide full behavior
737 backward compatibility).
738 - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
739 unsafe and caused compilation error with clang 2.x).
740 - Bugfix: only process the latest MIDI program change event.
741 - Introducing the LSCP shell, which provides convenient control of the
742 sampler from the command line by providing LSCP aware features.
743 - VirtualMidiDevice: Added support for program change.
744 - VirtualMidiDevice: Added support for bank select (MSB & LSB).
745 - VirtualMidiDevice: Added support for pitch bend.
746 - Aftertouch: extended API to explicitly handle channel pressure and
747 polyphonic key pressure events (so far polyphonic pressure was not
748 supported at all, and channel pressure was rerouted as CC128 but not
749 used so far).
750 - Added initial support for real-time instrument scripts. The script VM
751 code is shared by all sampler engine implemementations, however only the
752 gig file format currently provides support for storing instrument scripts
753 (as LinuxSampler extension to the original GigaStudio 4 format).
754
755 * Gigasampler format engine:
756 - implemented the "round robin keyboard" dimension
757 - fixed round robin and random dimensions for cases when number of
758 dimension zones is not a power of two
759 - made round robin use a counter for each region instead of each
760 key
761 - bugfix: pitch LFO controller "internal+aftertouch" was broken
762 - bugfix: filter keyboard tracking was broken
763 - filter performance fix (an unnecessary copy was made of the
764 filter parameters in each sub fragment)
765 - handle special case when pan parameter in gig file has max or
766 min value
767 - Exclusive Groups: don't ever stop voices of the same note,
768 doesn't sound naturally with a drumkit
769 - fixed EG1 modulation when attack or release is zero
770 - Fixed support for 'aftertouch' attenuation controller.
771 - Fixed crash that happened with velocity split sounds under certain
772 conditions (see also previous commit on libgig).
773 - fixed behaviour of filter LFO
774
775 * SFZ format engine:
776 - Initial implementation (not usable yet)

784 - fixed error when unloading instrument with same sample used by
785 multiple regions
786 - added some opcode aliases, like loopmode for loop_mode, to be
787 more compatible
788 - added support for trigger=release and rt_decay
789 - added support for off_mode=normal
790 - added support for random, seq_position, seq_length and volume

805 - added support for loop_mode=one_shot
806 - fixed playback of 16 bit wav files on big endian CPUs
807 - added support for Ogg Vorbis sample files
808 - use loop markers from sample file if loop_start and loop_end are
809 not set in sfz file
810 - implemeted filters. Filter types: lowpass, bandpass, bandreject
811 and highpass. 1, 2, 4 and 6 pole filters. Opcodes: fil_type,
812 cutoff, resonance, fil_veltrack, fil_keytrack, fil_keycenter,
813 cutoff_cc, cutoff_chanaft.
814 - bugfix: zero ampeg_sustain didn't work

1003 the driver will automatically connect to other CoreMIDI clients' ports
1004 (e.g. external MIDI devices being attached to the Mac)
1005 - added support for MIDI note on velocity filter
1006 - CoreMIDI: fixed memory deallocation error
1007 - Fixed variable underflow in VirtualMidiDevice, which caused graphical
1008 virtual keyboards in frontends / instrument editors being stuck.

1078 - Added support for moving cursor left/right with arrow keys.
1079 - Added support for built-in LSCP reference documentation, which will
1080 automatically show the relevant LSCP reference section on screen as soon

1141 - bugfix: playing a note while changing the instrument could cause
1142 a crash, or give "Handing back unknown region" error messages
1143 - bugfix: calling SET VOICES (which Fantasia does on start and
1144 refresh) could cause instruments to be unloaded

1177 crashes and noise on such transitions).
1178 - ignore missing LADSPA paths without ignoring valid LADSPA paths
1179 (fixes #208)
1180 - Fixed bug in LSCP grammar definition which caused a statement like
1181 "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
1182 practically irrelevant, however it caused problems with the new LSCP
1183 shell's auto completion feature).
1184 - Fixed MIDI program change messages being ignored if quickly executed
1185 after each other (fixes #231).
1186
1187 Version 1.0.0 (31 July 2009)
1188
1189 * packaging changes:
1190 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
1191 causing e.g. the libgig test to fail when
1192 "./configure --disable-jack-driver" was used
1193 (patch by Alexis Ballier)
1194 - fixed compilation with gcc 4.3
1195 - fixes for building on OS X (thanks to Ebrahim Mayat for testing)

1200 - minor fix in configure for mmsystem.h detection on MinGW
1201 - Windows: look for editor plugins and Fantasia using base
1202 directory of liblinuxsampler dll (look in the same directory and one
1203 directory above)
1204 - configure script fix: removed unconditional use of SSE
1205 - fixed building with sqlite installed in a non-standard directory
1206 - when cross-compiling, don't try to create instruments.db
1207 - fix for new mingw-w64 version, which has usleep
1208
1209 * general changes:
1210 - bugfix: on some POSIX systems instrument editor plugins refused to
1211 load as we used a non-portable Linux specific struct field
1212 (fixes bug #70, patch by Ronald Baljeu)
1213 - fixed endless loop which occured when loading an instrument editor
1214 plugin DLL on Windows systems failed
1215 - fixed memory leaks that occurred when liblinuxsampler was unloaded
1216 - optimized the SynchronizedConfig class so it doesn't wait
1217 unnecessarily long after an update
1218 - added support for notifying instrument editors on note-on / note-off
1219 events (e.g. to highlight the pressed keys on the virtual keyboard
1220 of gigedit)
1221 - added support for triggering notes by instrument editors (see above)
1222 - be verbose on DLL load errors (on Linux)
1223 - fixed di-harmonic triangle LFO implementation (this LFO implementation
1224 is only used by very few systems, most pick the int math
1225 implementation, which is usually faster)
1226 - fixes for audio drivers with varying buffer sizes
1227 - experimental support for running LinuxSampler as a DSSI, LV2 and
1228 VST plugin
1229 - notification events for stream/voice count statistics are now sent
1230 only when there are actual changes
1231 - added memory ordering constraints to improve stability on
1232 multi-core and multi-cpu systems
1233 - maximum voices and disk streams can now be altered at runtime
1234 - fixed CPU feature detection on x86_64 (maybe fixes #108)
1235 - automatic stacktrace mechanism is now turned off by default and can
1236 be switched on by command line option "--stacktrace" (the automatic
1237 stacktrace mechanism seems to be broken on most systems at the moment)
1238 - C++ API method InstrumentManager::LaunchInstrumentEditor() now returns
1239 a pointer to the launched InstrumentEditor object
1240 - added optional 3rd party user data parameter for following
1241 liblinuxsampler C++ API methods: InstrumentEditor::Main(),
1242 InstrumentEditor::Launch(),
1243 InstrumentManager::LaunchInstrumentEditor()
1244 - theoretical fix: made SynchronizedConfig follow C++0x memory
1245 model more strictly
1246 - fixes for using large audio device buffers
1247 - Windows: add the installation directory to the DLL search path
1248 when loading an editor plugin (solves problems with VST and
1249 gigedit on systems with other GTK versions installed)
1250 - updated linuxsampler man page
1251
1252 * audio driver:
1253 - removed the nonsense audio channel constraint (which was hard coded to
1254 max. 100 audio channels) for most audio drivers
1255 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
1256 opposed to the LSCP specs
1257 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
1258 reflected the wrong value
1259 - fixed a memory management bug in ASIO driver
1260 - Makefile fix: JACK_CFLAGS wasn't used
1261 - JACK: use jack_client_open instead of the deprecated
1262 jack_client_new
1263 - added (experimental) CoreAudio driver
1264 - applied old fixes to the ASIO driver that were included in the
1265 previous binary release but accidentally never committed to CVS
1266 (fixes #117)
1267 - fixes for ASIO on mingw-w64 (iasio wrapper is not needed on
1268 win64)
1269 - VST: added support for sample rate and buffer size changes
1270 - VST: close editor (Fantasia) when the VST is removed
1271 - VST: avoid opening Fantasia more than once for each VST instance
1272 - VST: export main function as "main" on Linux too (fix for
1273 energyXT)
1274 - VST: changed number of output channels from one stereo to 16
1275 stereo
1276 - added channel routing, fxsends and midi maps to the settings
1277 stored in the plugin state
1278 - performance optimization of AudioChannel::MixTo() and
1279 AudioChannel::CopyTo() methods using GCC vector exensions
1280 (if available)
1281 - ASIO fixes: avoid initializing the device twice, avoid throwing
1282 exception when getting parameters from a disconnected device
1283
1284 * MIDI driver:
1285 - added JACK MIDI driver
1286 - dispatch bank select as ordinary CC as well, the user might seriously
1287 want to (mis)use it for some purpose ("fixed" in all current MIDI
1288 input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
1289 - bugfix: pitch bend wasn't working with JackMidi, VST, LV2, MME,
1290 CoreMidi or AU
1291 - fixed mingw-w64 compilation error in MME driver
1292 - made program change handling in MIDI thread real-time safe by
1293 moving the logic to a non-RT thread
1294 - fixed minor memory leak in ALSA driver
1295
1296 * instruments database:
1297 - avoid time consuming samples scanning when adding instruments
1298 to the instruments database
1299 - added support for handling lost files in the instruments database
1300 - Implemented option for adding instruments in separate directories
1301 in the instruments database
1302 (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
1303 - work-around for missing fnmatch function on Windows to make
1304 instrument database compilable
1305 - added instrument database support on Windows
1306 works with both standalone mode and VST plugin.
1307 the instruments DB file is located in
1308 %USERPROFILE%\.linuxsampler\instruments.db which allows different
1309 databases for each windows user
1310 if no DB is present it automatically creates the .linuxsampler subdir
1311 and then creates an empty DB
1312 - fixed recursive import, which was broken on Windows
1313
1314 * Gigasampler format engine:
1315 - fixed a memory leak that could happen when a channel was deleted
1316 while notes were playing
1317 - made it possible to load an instrument even if the audio thread
1318 isn't running
1319 - added partial support for the "Controller Triggered" MIDI rule,
1320 enough for piano gigs with pedal noise samples
1321 - minor fix: only mark FX sends as being modified if really the
1322 respective FX send MIDI controller was used
1323 - added support for GM global device volume SysEx message
1324 (can be selected at compile time to either apply globally to the
1325 whole sampler [default] or only to the sampler channels that are
1326 connected to the respective MIDI input port the SysEx message arrived
1327 on)
1328 - bugfix: notes triggered at position 0 in the audio buffer were
1329 sometimes wrongly killed in the same buffer, causing no sound to
1330 be played
1331 - added support for chromatic / drumkit mode Roland GS Sysex message
1332 which is usally used to switch a part between chromatic sounds and
1333 drumkit sounds (as opposed to their common default setting of MIDI
1334 part 10 being a drumkit part and all other ones chromatic parts), in
1335 LS however one can switch between the first 16 MIDI instrument maps
1336 defined for the sampler
1337 - made it possible to create multiple sample channels even if the
1338 audio thread isn't running
1339 - fixed crash when removing channel with active voices (#116)
1340 - bugfix: on sample reference changes (instrument editor), only
1341 un-cache the respective sample if it's really not used by any
1342 sampler engine anymore
1343 - re-cache samples in case they were changed by an instrument editor,
1344 e.g. when a sample was added while playing (#82)
1345 - fixed hanging notes which occured when note-off event had the exact
1346 same time stamp as the voice's note-on event and occured both in the
1347 same audio fragment cycle (fixes bug #112)
1348 - added support for the "fine tune" and "pitch bend range"
1349 instrument-level gig parameters
1350 - fixed minor artifacts in pitch bend handling
1351 - added support for GS Reset SysEx message
1352 - allow gig files to use unlimited downward pitch shifting
1353 - added a limit check for upward pitch shifting
1354 - bugfix: sometimes, when playing a note twice fast, the second
1355 note was silent
1356 - fixed crash happening when a pitch bend event arrived at the
1357 same time a new instrument was loading
1358
1359 * LSCP server:
1360 - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
1361 react on MIDI data arriving on certain sampler channels (so far only
1362 Note-On and Note-Off events are sent via this LSCP event)
1363 - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
1364 react on MIDI data arriving on certain MIDI input devices (so far only
1365 Note-On and Note-Off events are sent via this LSCP event)
1366 - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
1367 SET DB_INSTRUMENT FILE_PATH
1368 - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
1369 frontends to send MIDI messages to specific sampler channel
1370 - added two additional fields to GET FILE INSTRUMENT INFO command -
1371 KEY_BINDINGS and KEYSWITCH_BINDINGS
1372 - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
1373 was incorrect
1374 - Optimized the retrieval of the MIDI instrument mappings
1375 - added new LSCP command "SET VOICES" to globally alter the maximum
1376 amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
1377 be triggered respectively
1378 - added new LSCP command "SET STREAMS" to globally alter the maximum
1379 amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
1380 which will be triggered respectively
1381 - bugfix: retry if "select" returns EINTR (this fixes a crash when
1382 a gigedit file dialog is opened)
1383 - close all connections when LSCPServer is deleted
1384 - hard close of all sockets on exit
1385 - bugfix: SET CHANNEL MIDI_INPUT_TYPE didn't work with the MME
1386 driver
1387
1388 * Bug fixes:
1389 - fixed a crash which occurs when removing a sampler channel waiting
1390 to start instrument loading after another channel
1391 - fixed a crash which occurs when removing a sampler channel with
1392 instrument loading in progress (bug #113)
1393 - fixed termination caused by uncaught exception when adding MIDI
1394 instrument with PERSISTENT load mode
1395 - fixed possible iterator invalidations when resetting the sampler
1396 - fixed memory leaks when issuing the following LSCP commands:
1397 GET AUDIO_OUTPUT_DRIVER INFO
1398 GET AUDIO_OUTPUT_DRIVER_PARAMETER INFO
1399 GET MIDI_INPUT_DRIVER INFO
1400 GET MIDI_INPUT_DRIVER_PARAMETER INFO
1401 - fixed possible compilation error when sqlite is not present
1402 - fixed orphaned pointers when setting maximum voices limit (bug #118)
1403 - fixed crash when changing the audio output device of a sampler
1404 channel with loaded instrument and start playing notes
1405 - fixed endless loop in Engine::SuspendAll() (bug #120)
1406 - fixed a low-level atomic load function that was broken on 64-bit
1407 PowerPC, which probably could cause crashes on that platform
1408 - fixed a memory management error which could cause a crash when a
1409 plugin was unloaded
1410 - bugfix: two private structs had the same name, which could cause
1411 problems if the linker chose the wrong constructor
1412 - fixed low-level ConditionServer usage bug that caused lockups on
1413 Windows
1414
1415
1416 Version 0.5.1 (6 December 2007)
1417
1418 * packaging changes:
1419 - added autoconf checks for pthread library
1420 - added autoconf check for pthread bug found on certain NPTL-enabled
1421 glibc versions (see Gentoo bug report #194076)
1422 - added autoconf checks for MS Windows
1423
1424 * general changes:
1425 - bugfix: the thread used by an editor plugin didn't die when the
1426 editor closed
1427 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
1428 out all the space. operator--() did not apply size_mask after
1429 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
1430 order to avoid problems with the _NonVolatileReader functions.
1431 - bugfix: Stream.h: added a missing divide by BytesPerSample in
1432 GetWriteSpace(). Since this function is currently only used in
1433 the stream's qsort() compare function, it didn't trigger any
1434 bugs.
1435 - Resampler.h, Synthesizer.h: cubic interpolation now works in
1436 24bit mode too. Faster method to read 24bit words on little
1437 endian machines (x86): replaced 3 byte reads + shifts with a 1
1438 unaligned 32bit read and shift
1439 - experimental support for MS Windows (MIDI input via MME, AUDIO
1440 output via ASIO)
1441 - made handling of SIGINT signal (Ctrl-C) a bit more robust
1442 - support for monitoring the total number of active disk streams
1443 (new LSCP commands: GET TOTAL_STREAM_COUNT,
1444 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
1445
1446 * AUDIO driver:
1447 - added Windows ASIO low latency audio driver
1448
1449 * MIDI driver:
1450 - added MME Windows MIDI driver
1451
1452 * LSCP server:
1453 - added support for Windows style path / filenames, however with
1454 forward slash path separators instead of backslash
1455 (i.e. "C:/foo/bar.gig")
1456 - allow naughty liblscp to send non-string device parameters within
1457 apostrophes as well
1458 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
1459 "LIST FILE INSTRUMENTS <file>" and
1460 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
1461 about an arbitrary instrument file on the system where the sampler is
1462 running on
1463
1464 Version 0.5.0 (15 October 2007)
1465
1466 * packaging changes:
1467 - config.h is not going to be installed along with liblinuxsampler's
1468 API header files anymore
1469 - only the API relevant header (and source) files will be exported to
1470 the Doxygen API documentation (explicitly listed in Doxyfile.in)
1471 - added completely new XCode project files for Mac OSX which is now
1472 capable to execute our autoconf environment, thus no need anymore
1473 to maintain the compile time configuration file (osx/version.h) for
1474 OSX manually (patch by Toshi Nagata)
1475 - fixed buggy boolean --enable-foo / --disable-foo configure script
1476 parameters
1477 - global.h now only covers global definitions that are needed for the
1478 C++ API header files, all implementation internal global definitions
1479 are now in global_private.h
1480 - atomic.h is not exposed to the C++ API anymore
1481 - no need to include config.h anymore for using LS's API header files
1482 - fixed warnings in API doc generation
1483
1484 * general changes:
1485 - replaced the old, confusing MIDI program change mechanism by a
1486 flexible MIDI instrument mapper which allows to map arbitrary
1487 (MIDI bank, MIDI program) pairs with arbitrary
1488 (engine type, instrument file, file index) triplets which will be
1489 loaded on the respective channel when such MIDI program change
1490 messages arrive, beside that, each entry allows to define a life-time
1491 strategy for the instrument, so the user can define whether the
1492 instrument should i.e. be permanently loaded (to be able to switch
1493 quickly among sounds) or i.e. loaded just on demand when the
1494 respective program change arrives (to safe RAM space), as well as a
1495 global volume factor for each entry, so the user can adjust the volume
1496 dynamic of his mapped instrument collection without having to modify
1497 the instrument files, also one can manage arbitrary amount of such
1498 MIDI instrument maps and assign each sampler channel individually
1499 a certain map, so that i.e. separation of normal instruments and
1500 drumkits is possible
1501 - new notification events for tracking changes to audio/MIDI devices,
1502 MIDI instrument maps, MIDI instruments, FX sends, global volume.
1503 - sampler was limited to load max. 200 instruments in the background
1504 due to a constant size RingBuffer FIFO which is now replaced by a
1505 dynamic (unlimited) size std::list FIFO
1506 - added FX sends, these allow to route audio signals to arbitrary audio
1507 output channels for being processed by external effect processors
1508 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
1509 controllers
1510 - global (sampler wide) volume can now be controlled at runtime
1511 - Implemented new, improved notification system
1512 - fixed compilation errors regarding OSX
1513 (patch by Toshi Nagata)
1514 - implemented instruments database
1515 - added support for escape sequences to the instruments database
1516 - added highly experimental support for on-the-fly instrument editing
1517 within the sampler's process (by using instrument editor plugins),
1518 you'll notice the new "Registered instrument editors:" message on
1519 startup, added a new LSCP command:
1520 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
1521 to spawn a matching instrument editor for the instrument on the
1522 given sampler channel, the plugin path can be overridden at compile
1523 time with ./configure --enable-plugin-dir=/some/dir
1524 - added experimental code for synchronizing instrument editors hosted
1525 in the sampler's process to safely edit instruments while playing
1526 without a crash (hopefully) by either suspending single regions
1527 wherever possible or if unavoidable whole engine(s)
1528 - fixed several issues in fundamental "Thread" class: set scheduling
1529 policy and priority on thread level, set a minimum stack size for
1530 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
1531 threads simply inherited properties of starting thread instead of
1532 setting their own policy and priority
1533 - minor fix in our automatic stack trace mechanism on crashes, the
1534 main process did not wait for the stack trace process to finish
1535 its output
1536 - fixed some minor memory leaks
1537 - reenabled assembly features support, at the moment only for
1538 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
1539 - minor assembly fix in x86 features detection (don't use the PIC
1540 register, to avoid relocations in the text segment at runtime)
1541 - POSIX callback functions of Thread.h are hidden
1542
1543 * MIDI driver:
1544 - dispatch bank select (MSB and LSB) messages
1545
1546 * audio driver:
1547 - the ALSA audio output driver parameters now reflect the correct
1548 parameter value ranges for the respective selected sound card
1549 (patch by Till Wimmer, a bit fixed and extended)
1550
1551 * Gigasampler format engine:
1552 - if a filter is used and EG2 finishes before EG1, let the voice
1553 die when EG2 has finished (this fixes a problem with clicks and
1554 voice starvation for some gigs)
1555 - playback is no longer disabled during instrument loading
1556 - all notes playing on a channel that changes its instrument keep
1557 playing with the old instrument until they get a note off
1558 command
1559 - EG fix: a release value of zero could cause noises or crash
1560 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
1561 - EG fine tuning: when attack is zero the EG starts at a level
1562 above max sustain level, which means that there is a decay phase
1563 even if sustain is 100%
1564 - more EG fixes: the level could sometimes go below zero and cause
1565 noises or crashes
1566 - minor fix of EGDecay (patch by Toshi Nagata)
1567 - fixed compiler error when --enable-override-filter-type was
1568 supplied to the configure script (fixes #46)
1569 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
1570 instead of a fix value
1571 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
1572 127 (solo mode) only kill voices if the respective mode really
1573 changed
1574
1575 * LSCP server:
1576 - fixed compile time error for old Bison versions
1577 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
1578 - parser now supports extended ASCII character set
1579 (up to ASCII code 255, i.e. includes now umlauts and accents)
1580 - filename arguments in LSCP commands now allow to use escape
1581 sequences, that is directly literal as one of: \', \", \\, \n, \r,
1582 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
1583 code value like \xf2) (fixes bug #24)
1584 - the following LSCP commands now also support escape sequences for at
1585 least one of their text-based parameters (i.e. name, description):
1586 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
1587 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
1588 "SET DB_INSTRUMENT_DIRECTORY NAME",
1589 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
1590 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
1591 "FIND DB_INSTRUMENT_DIRECTORIES"
1592 - returns verbose syntax errors (line and column where syntax error
1593 occured, the unexpected character and the actually expected, possible
1594 character(s), the latter only if less than 5 possibilities)
1595 - made sure that LSCP syntax is not affected by gigedit locale
1596 settings
1597 - bugfix regarding strings parameter lists: all comma separated lists
1598 of strings were treated as being one string containing commas
1599 (fixes #57)
1600
1601 * Bug fixes:
1602 - fixed crash occurring on certain LSCP scripts (Bug 39)
1603 - another thread safety fix for lscp "load engine" and "set
1604 channel audio output device"
1605 - fixed a crash which occurs when reassigning the same engine
1606 on a sampler channel with connected MIDI device
1607 - fixed a crash which occurs when changing the number of ports of a MIDI
1608 device connected to a sampler channel to number less then or equal
1609 to the index of the port to which the sampler channel is connected.
1610 - The previous bindings were not been disconnected when altering
1611 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
1612 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
1613 - The active stream/voice count statistic was incorrect.
1614 - notification events were not been sent for some sampler
1615 channel changes
1616 - added default min and max values to restrict the number of allowed
1617 audio output channels and MIDI input ports
1618 - the connection to the PCM interface is now closed when destroying
1619 an audio output device
1620 - files with slash in their path or filename could not be loaded
1621
1622 * test cases:
1623 - updated and fixed (haven't been touched in a while)
1624
1625 Version 0.4.0 (24 November 2006)
1626
1627 * packaging changes:
1628 - changed deprecated copyright attribute to license; added ldconfig
1629 to post-(un)install steps; added devel package for liblinuxsampler;
1630 to linuxsampler.spec (RPM)
1631 - install necessary development header files for allowing 3rd party
1632 applications to link against liblinuxsampler
1633 - liblinuxsampler's API documentation can be generated with 'make docs'
1634 (Doxygen required)
1635 - added benchmark to automatically detect the best triangle LFO
1636 implementation (currently either an integer math solution or a
1637 di-harmonic approximation), automatic detection can be overriden
1638 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
1639 configure script argument though (mandatory for cross-compilation)
1640 - do not automatically pick optimized gcc flags if the user already
1641 provided some on his own (as CXXFLAGS)
1642 - added compile time option to disable processing of All-Notes-Off MIDI
1643 messages
1644 - added compile time options to allow disabling the various audio and
1645 MIDI drivers
1646 - fixed automatic GCC CPU switch detection on PPC
1647 (patch by Ebrahim Mayat)
1648
1649 * Gigasampler format engine:
1650 - extensive synthesis optimization
1651 (reimplementation of EGs and LFO(s), removed synthesis parameter
1652 prerendering and the synthesis parameter matrix in general, splitting
1653 each audio fragment into subfragments now where each subfragment uses
1654 constant pitch and filter coefficients. The volume coefficient is
1655 linearly interpolated inside a subfragment, unless
1656 --disable-interpolate-volume is set.)
1657 - fine tuning of the EG modulation parameters
1658 - improved filter cutoff calculation by adding support for the
1659 following gig parameters: Cutoff freq (used when no cutoff
1660 controller is defined), Control invert, Minimum cutoff, Velocity
1661 curve and Velocity range. The keyboard tracking now scales
1662 cutoff frequency instead of resonance.
1663 - added support for gig parameter Resonance.
1664 - fixed bug in sysex handling (patch by Juan Linietsky)
1665 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
1666 which can be overridden with --enable-global-attenuation
1667 - EG fixes: made the length of "attack hold" stage more
1668 accurate. Release stage can now start before attack stage
1669 ends. Cancel release didn't work when sustain was zero. Attack
1670 time now has a minimal value to prevent clicks.
1671 - fixed pitch changes larger than one octave
1672 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
1673 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
1674 all modes can be altered via standard GM messages, that is CC5 for
1675 altering portamento time, CC65 for enabling / disabling portamento
1676 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
1677 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
1678 parameter) and crossfade
1679 - added support for the "attenuation controller threshold" gig
1680 parameter
1681 - added smoothing of volume changes caused by control change
1682 messages
1683 - sample loop parameters are now taken from the DimensionRegion
1684 instead of the wave chunk
1685 - fixed keyswitching for v3 gigs with a number of keyswitch splits
1686 not equal to a power of two
1687 - reimplementation of the filter algorithm. The new filter is more
1688 accurate and supports all gig filter types, including bandreject
1689 and lowpass turbo.
1690 - real support for 24 bit samples - samples are not truncated to
1691 16 bits anymore
1692 - support for aftertouch (channel pressure, not polyphonic
1693 aftertouch)
1694 - LFO1 behaviour fixed (dampening from max volume instead of
1695 amplifying from 0)
1696
1697 * LSCP server:
1698 - fixed application exit on broken pipe error (fixes bug #20)
1699 - fixed the notification messages delay due to lack of
1700 network activity (fixes bug #26)
1701 - fixed parser bug which occured on space(s) within device parameters
1702 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
1703
1704 * audio driver:
1705 - added aRts audio output driver (by no means RT safe)
1706
1707 * MIDI driver:
1708 - fixed legacy sysex code which caused dispatching of MIDI SysEx
1709 messages several times instead of once
1710 - API extension for MIDI drivers which already supply exact time stamps
1711 for events (i.e. for offline rendering based MIDI drivers)
1712 - added checks for bad MIDI data
1713
1714 * linuxsampler application:
1715 - show available sampler engine types on startup
1716
1717 * general changes:
1718 - support for muting sampler channels and solo mode of the same, two new
1719 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
1720 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
1721 introduced for this, the behavior is the same like on a mixer console
1722 (patch by Grigor Iliev, a bit adjusted). Also added configure option
1723 --enable-process-muted-channels which can be used to enable the
1724 processing of muted channels.
1725 - support for sostenuto pedal
1726 - support for monitoring the total number of active voices
1727 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
1728 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
1729 - fixed some memory management errors
1730 - fixed some concurrency problems that could lead to crashes when
1731 LSCP commands were executed
1732 - fixed crash when instrument loading failed previously on the same
1733 sampler channel (fixes bug #36)
1734
1735 Version 0.3.3 (15 July 2005)
1736
1737 * packaging changes:
1738 - fixed compilation with gcc 4.0
1739
1740 * Gigasampler format engine:
1741 - LFO preprocessing was performed even though the respective LFO was
1742 disabled by the instrument patch (minor efficiency fix)
1743 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
1744 for volume ramp downs in the same fragment (needed for current voice
1745 stealing implementation) then simply inform the user with a warning
1746 about possible click sounds and reduce the volume ramp down
1747 appropriately instead of cancelling the audio device connection
1748
1749 Version 0.3.2 (24 June 2005)
1750
1751 * packaging changes:
1752 - updated autotools build files to compile on OS X
1753 (conditional compilation of CoreMIDI and MidiShare drivers)
1754 - hand-crafted assembly optimization code can be disabled with
1755 './configure --disable-asm' (definitely not recommended)
1756 - fixed 'make dist' rule to include all necessary files
1757 - require automake (>= 1.5) for 'make -f Makefile.cvs'
1758 (due to 'dist-bzip2' automake option)
1759
1760 * Gigasampler format engine:
1761 - support for the gig parameters for "release velocity response" curves
1762 - fine tuning of the EGADSR envelope
1763 - volume of release triggered samples now depends on note-on velocity,
1764 note length and gig parameter "release trigger decay" instead of
1765 note-off velocity.
1766 - revised voice stealing
1767 (fixes crash and endless loop caused by voice stealing)
1768 - don't reset scale tuning on instrument or audio output device change
1769 - handle key group conflicts right at the beginning of each fragment
1770 instead of when the respective voice is actually launched
1771 (fixes undefined behavior if stolen voices belonged to a key group -
1772 this case was followed by a "killed voice survived" error message)
1773 - fixed minor issue with null/silence samples
1774 (those stole voices even though they don't need a voice at all which
1775 resulted in "voice stealing didn't work out" messages)
1776 - don't reset volume, pan, pitch and MIDI controller values on
1777 instrument or audio output device change
1778
1779 * LSCP server:
1780 - fixed some crashes (patch by Grigor Iliev, fixes #19)
1781 - fixed LSCP event "CHANNEL_INFO" notification
1782 (e.g. did not notify on volume changes or MIDI program change events)
1783
1784 * linuxsampler application:
1785 - added command line parameters --lscp-addr and --lscp-port to override
1786 default IP address and port of LSCP server
1787
1788 Version 0.3.1 (24 May 2005)
1789
1790 * initial release
